Cant read/load more than 256 rule pharse in xml file

Question

Hi all, i am using a c# application to read/load from a xml file

here are the xml file content, like from this example http://msdn.microsoft.com/en-us/library/ms723634%28v=vs.85%29.aspx

<GRAMMAR>
    <DEFINE>
    </DEFINE>
<RULE NAME="HelloWorld" TOPLEVEL="ACTIVE"><P>HelloWorld</P></RULE>
<RULE NAME="HelloWorld2" TOPLEVEL="ACTIVE"><P>HelloWorld2</P></RULE>
<RULE NAME="HelloWorld3" TOPLEVEL="ACTIVE"><P>HelloWorld3</P></RULE>
</GRAMMAR>

and so on until rule pharse HelloWorld256, my application still can read/load it, but after add the 257 rule pharse, it cant read/load anything,
is there a way so i can add more than 256 rule pharse in a xml file?








or maybe the alternative way, by open 2 xml files together, that each have 256 rule pharse, this is my c# application part, that load the grammar
// load the grammar
SAPIGrammarFromFile("XMLhelloworld.xml");

i already tried these but no one works

// load the grammar
SAPIGrammarFromFile("XMLhelloworld.xml");
SAPIGrammarFromFile("XMLhelloworld2.xml");

// load the grammar
SAPIGrammarFromFile("XMLhelloworld.xml") & ("XMLhelloworld2.xml");

// load the grammar
SAPIGrammarFromFile("XMLhelloworld.xml" & "XMLhelloworld2.xml");








please help which ever methode that can works
